  • Material
    The material types of waterproof membrane include Ethylene-Copolymer-Bitumen (ECB), Poly-Vinyl-Chloride (PVC), or other material, such as EVA and LDPE. The physical and chemical properties can fully meet all the standards requirements in Table I or Tabl.
    There should be layers revealing cracks on one side and the color should contrast sharply with the waterproof membrane for easy identification of cracks by naked eyes.

    Size
    The length of waterproof membrane should be cut based on the tunnel perimeter. There should be no vertical joint except the intersection or special design.
    Material requirements and testing standard: As Table I and II.
